Fifth Fleet

The Star Army of Yamatai's Fifth standard fleet, while originally formed in YE 30, underwent a massive re-organization during YE 34 in order to solidify its mission as an assault fleet, and Yamatai's premier ground-combat force. It is commanded by Taisho Johnathan Whitmoor.

The Fifth fleet's mission is to protect, serve, and empower the Yamatai Star Empire by keeping safe the planets through the use of combined arms based on the use of infantry, armor, and air.


The old Fifth Fleet was commanded by Taisho Hoshi Koigokoro and was stationed within Python Sector's Tabidatsu System. Because of this, its symbol is a Python.


The Fifth fleet uses a different unit structure for its ground troops than other Yamataian fleets. Instead of using Centuries and Legions, it uses a more traditional, though somewhat modified military structure to organize and administrate its forces.
